  • Patent number: 11919570
    Abstract: To simultaneously avoid contact with a front subframe and secure a connection space for a harness, a front subframe has a right and left pair of side frame sections, each of which is located in front of and below a dashboard. A converter and a vehicle component are provided behind a rear end portion of one of the side frame sections. The converter is arranged along a lower surface of a floor panel, and the vehicle component is arranged adjacent to rear of the converter. The converter is arranged in a vertically inclined state, a front-end portion of the converter is located higher than the rear end portion of the side frame section, and a rear end portion of the converter is located lower than the vehicle component.

  • Publication number: 20240054668
    Abstract: An object is to obtain three-dimensional shape data with high accuracy from three-dimensional shape data representing an approximate shape of an object. Three-dimensional shape data of an object captured in a plurality of captured images whose viewpoints are different is obtained. Further, surface three-dimensional information on the object is derived based on the plurality of captured images. Then, the derived surface three-dimensional information is selected based on a distance from the shape surface of the object represented by the three-dimensional shape data.

  • Publication number: 20240054747
    Abstract: An object is to obtain three-dimensional shape data with high accuracy from three-dimensional shape data representing an approximate shape of an object.

In the image processing apparatus, data, which correspond to N frames (N is an integer not less than 2), in units of frames including a plurality of three-dimensional models per frame is acquired. Then, shape registration processing is performed for the acquired three-dimensional models corresponding to the N frames by using information indicating a correspondence relationship of the three-dimensional models between frames of the N frames.

  • Publication number: 20230245343
    Abstract: Resulting from a reduction in the accuracy of a feature point obtained from a viewpoint inclined with respect to the front direction of an object, the estimation accuracy of three-dimensional coordinates of the feature point is reduced. Consequently, from each of a plurality of images captured from a plurality of viewpoints, the feature point of the object is detected and attribute information indicating which area of the object the detected feature point belongs to is appended to the detected feature point. Then, for each of the same attribute information, the three-dimensional coordinates of the feature point are calculated by using two-dimensional coordinates of the feature point on the image corresponding to the viewpoints not more than the plurality of viewpoints and not less than two.

  • Publication number: 20230156177
    Abstract: An object is to provide a format of a volumetric video with which it is possible to efficiently perform selective drawing of a specific object. Volumetric video data consisting of a sequence of frames, each frame including object shape data and tracking information indicating a change of each object between frames, each object corresponding to the shape data, are obtained. Then, based on the tracking information, metadata that associates each of the objects and the shape data in each frame is generated and the volumetric video data including the metadata is output.
